I wonder if there is any correlation between how much people care about their idea, ending up on this thread, and their likelihood of getting an interview.
There is certainly a correlation about caring about the idea and success . But ideally you should be focused on building your product, which is more important than any investor.
Easier said than done, specially today (I firmly believe in that, and am here after all).
Getting feedback is always important! As is looking at what everyone else is doing, generating some ideas and figuring out places where you need to improve.
